PHILIP DH. DRESSLER, 0F ZANESVILLE, OHIO. ASSIGNOR TO AMERICAN DRESSLER TUNNEL KILNS, INQ, OF NEW YORK, N. Y., A CORPORATION 0F NE'W YORK.

GAS-PRODUCER CONDUIT.

Application'filed May 28, 1919.

T 0 all whom 'Ztjfldfl/ concern 'Be it known that I, PHILIP DH. DRESSLER, a subject of the King of Great Britain, and resident of Zanesville, in the count-y of Muskingum and State of Ohio, have invented certain new and useful Improvements in Gas-Producer Conduits, of which the following is a specification.

The object of my present invention is to provide a simple and effective arrangement of ducts and chambers adapted to receive the hot gases from a gas producer or battery of gas producers, and to convey these gases with but slight reduction in temperature to the furnace chamber or other apparatus 111 which they are to be burnt, and adapted also to serve as cleaning ducts in which a large portion of the pitch. tar and other impurities in the gas may deposit and from which the deposited impurities may be removed out from time to time without interfering with the continuous passage of gas from the producers to the furnace or other apparatus utilizing such gas.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention. however. and the advantages possessed by it reference should be had to the accompanying drawings and descriptive matter in which I have illustrated a preferred embodiment of my invention.

of the drawings:

Figure 1 is a plan view of a battery of gas producers and the gas cleaning provisions therefor.

Fig. 2 is an end elevation of the apparatus shown in Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a section on the line 44 of Fig. 1 and of Fig. 3.

Fig. 5 is a section on the line 55 of Fig. 1 and of Fig. 3.

Fig. 6 is a section on the line 6-6 of Fig. 1 and of Fig. 3, and

Fig. 7 is a section taken similarly to Fig. 3 illustrating a modified construction.

In the drawings and referring first to Figs. 1-6, the gas producer plant shown comprises three producers A, each with its individual gas outlet or main A The three producer outlets A discharge each into one of a set of parallel horizontal passages B Specification of Letters Patent.

forming an extension of the corres )onding producer outlet A Each passage is provided with two ports B in its upper wall, each of these ports being controlled by a valve D (see Figs. 3 and 5). The two ports B from each passage B open into separate chambers C- and C arranged alongside of one another (see Fi 5) and opening at their lower ends respectively to chambers or ducts E and E as the lower ends C of the chambers C are shown opening into the chamber E in Fig. The chambers E and E are arranged side by side beneath the ducts B and extend at right angles to the latter. At one end the duct or chamber E is connected by a port E controlled by a valve H, and by a passage I to a stack J. The same end of the duct or chamber E is connected by port E also controlled by valve H, and by a passage I to the stack J. At its opposite end each of the chambers E and E isprovided with an air inlet opening normally closed by a valve K, and is connected by a gas outlet port, controlled by a correspoinling valve F. to a gas channel (l running to the kiln, furnace or other apparatus to which the cleaned gas is delivered for combustion. Advantageously a cleanout door G is provided at the end of the channel for inspection purposes and to admit air for burning out this passage. The walls of the gas cleaningducts and chambers are lined with suitable refractory material and are made of such thickness and material as to minimize the radiation of heat so that the cleaned gas is delivered to the passage G at a temperature but little below that at which the gas is delivered to the cleaning apparatus by the producer outlets A It will be understood that in the construction shown in Figs. 1-6 there are as many pairs of chambers C and as there are producers, and that instead of the three producers shown a larger number or one or two only may be employed. Holes C to permit inspection and the insertion of cleaning poker are provided in the top walls of the vertical portions of the passages C and C The chambers E and E are substantially larger in cross section than the passages B, C and (l. and in consequence of the reduction in velocity and the change in direction of the gas streams entering the chambers E and F. through the down coming portions of the passages C and C the pitch, tar,

' E and E is connected with the inlet pas carbon particles and ashes carried with the gas'into the chambers E and E largely settle out in these chambers. The pitch, tar and carbon parti les collecting .on the bottom and side walls of the chambers E and E may readily be burnt out from time to time. To thus clean either of the chambers E and E the corresponding valve H and air inlet damper K (see Fig. 3) are opened. The air enterin the chamber past the then open damper If unites in combustionwith the tar, pitch and carbon deposits and the resulting products of combustion are swept out of the chamber and discharged from the stack J by the draft created by the latter. In practice one of the chambers sages B, and the outlet passage G, by-the opening the proper valves,. for a period of two or three days or a week at a time, and during this period the other of the two chambers is disconnected from the gas inlet passages D and outlet passage G by the closure of the corresponding valves D and F. The burning out operation for each chamber occurs, of course, while it is disconnected from the gas inlet and outlet passages.

Instead of the three separate connections employed in the construction shown in Figs. 16 between the three main extensions B and each of the chambers E and E the latter may each be connected to the three main extensions as the chamber E is shown connected in Fig. "7. In the modification shown in Fig. 7 a single passage (A above and parallel to the chamber E is connected to the latter by two ports C Each of the three main extensions I3 is connected to the passageCA by a corresponding port ll Doors C are provided at the opposite ends of the passage CA to permit inspection. and the admission-of air for .burning out the channelwhen this becomes necessary or desirable. In the modification shownin Fig. 7 there is no vertical passage at the right hand side of the right hand main extension B corresponding to the down coming portion of. the right hand chamber of Figs. 1 and 3. In consequence the construction of Fig. '7 may be shorter and. hence less expensive to build than the construction of Figs. 1-6. The passages C and (A of Fig. 7 are somewhat easier to clean moreover, than are the corresponding passages of the construction shown in Figs. 1 to (5.

While in accordance with the provisions of the statutes I have illustrated and described the best form of my invention now known to me it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed with out departing from the spirit of my invention as set forth in the appended claims and that under some conditions certain features of my invention may be used to advantage without the corresponding use of other features.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

l 1. In a producer gas plant the combination with one or more producer gas outlets, of a pair of chambers, separate valved connections between each of said gas outlets and the two chambers, a gas outlet conduit, and separate valved connections from the two chambers to said conduit.

2. In a producer gas plant the combination with one'orv more producer gas outlets, a pair of chambers,-separate valved connections between each of said gas outlets and the two chambers, a gas outlet conduit, separate valved connections from the two chambers to said conduit,- a stack, separate valved connections between said chambers and said stack, and separate valved air inlets to said chambers.

3. In a producer gas plantthe c0mbina tion of a pair of horizontally elongated chambers arranged side by side, one or more gas inlet passages extending transversely to said chambers, a separate valved connection between each of said inlets and each of said chambers, a stack, separate valved connection between one end of each of said chambers and said stack, a valved air inlet at the opposite end of each of said chambers, and a separate valved gas outlet from each of said chambers.

4. In a producer gas plant, the combination of a pair of horizontally elongated gas cleaning chambers one ormore gas inlet passages extending transversely to said chambers, passages separately connecting each of said gas inlet passages to the two chambers, said connecting passages including portions above said gas inlet passages and portions extending downward past the gas inlet passages, and a valve for and con trolling the flow through each of said passages, a valved stack connection to one end of each of said chambers,-a valved air inlet to the opposite end of each of said chambers, and a valved gas outlet-from each of said chambers.
